Chiari malformation symptoms & treatment

Chiari malformations are defects in the area where the spine connects with the lower part of the brain, called the cerebellum. If the bottom of the skull isn’t formed properly, it can cause the cerebellum to push down on the spinal cord. This can block the flow of cerebrospinal fluid (CSF), a clear liquid that surrounds and protects the brain and spine.

Chiari malformation symptoms

Often Chiari malformation symptoms begin to occur during childhood or adulthood – although some people never experience any symptoms. Chiari malformation symptoms may include:

• Neck or head pain
• Balance and coordination problems
• Numbness in your arms or legs
• Blurred vision
• Trouble swallowing

Diagnosis of Chiari malformation

First, you’ll meet with your doctor for a physical exam. You’ll talk about your potential Chiari malformation symptoms, and your doctor may order imaging tests, such as an MRI or CT scan. If a buildup of CSF is putting pressure on your brain or spine, you may need to have the fluid drained as part of your Chiari malformation treatment plan.

Chiari malformation treatment options

Chiari malformation treatment options include:

• The Expanded Endonasal Approach (EEA), which does not require an incision. Instead, the fluid is removed using a thin tube inserted through the nostrils.
• Surgery to repair the defect. This usually requires a small cut in the back of the head.
